Adenomyoma is a term generally applied to nodular lesions showing proliferation of both epithelial and smooth muscle components. Despite its benign nature, ampullary adenomyoma is usually presented as biliary obstruction. Most cases are misdiagnosed as carcinoma or adenoma by preoperative endoscopic or radiologic procedure. Therefore, it is frequently treated with extensive surgery. To our knowledge, this is the first reported case in English literature of adenomyoma located in the peripancreatic orifice resulting in intermittent pancreatic duct obstruction and recurrent pancreatitis diagnosed by the endoscopic piecemeal resection.
Article: Adenomyoma of the jejunum[Show abstract] [Hide abstract]
ABSTRACT: Adenomyoma of the small intestine is an extremely rare condition characterized by abnormal glandular structures surrounded by smooth muscle. We report a case of adenomyoma of the jejunum. The patient was a 61-year-old female with cancer of the sigmoid colon and multiple liver cysts, who was sent to the operation room for exploratory laparotomy and sigmoidectomy. At surgery, a polypoid lesion was incidentally found in the lower jejunum, which was resected. On histologic examination, the morphologic features were typical of adenomyoma. However, new histopathological and immunohistochemistry features are described here, providing evidence that adenomyoma of the jejunum is a form of intestinal epithelial hamartoma.

ABSTRACT: Endoscopic therapy has emerged as an alternative to surgery for the subset of patients with acute recurrent pancreatitis whose disease is due to gallstones or other mechanical processes that obstruct the outflow of the pancreas. In this article, the authors review the specific situations in which endoscopic therapy might be useful in patients with acute recurrent pancreatitis.
